Will go a
little bit back and we will look for the permission and required windows
feature pre-requisites for better understanding above error message.

Before
you install/update your exchange system, you should have below permissions,

1.Schema Permission

2.Enterprise Admin

3.Domain Admin

Failure Description:
-

It’s recommended
and best practice to prepare Schema, AD and Domain Preparation well before on
the domain controllers in the production environment. Also, you have to run the
preparation on the root domain controller so that it will be replicated across
all child domains.

If you
didn’t prepare active directory preparation well ahead and you are doing part
of Exchange installation, then you will experience this issue when you don’t have
RSAT ADDS tool installed on the member server.
